Here we have the essentials of the story which Wagner wrought into his opera "Lohengrin" Only a few details need be added to make the plot complete. The meeting of Lohengrin and Elsa takes place on the banks of the river Scheldt in Brabant. The King has come to ask the help of the Brabantians against the Huns, who are invading Germany. He finds Brabant in a disturbed state. The throne is vacant; Count Frederick of Telramund, who has his eyes upon it, had offered his hand in marriage to Elsa, who, with her brother, Gottfried, had been left in his care on the death of their father, but had met with a refusal. He had then married Ortrud, a Frisian princess. She is the last of a royal line, but a pagan, and practises sorcery. To promote the ambition of herself and her husband, she has changed Gottfried into a swan by throwing a magical chain about his neck, and persuaded Telramund to accuse Elsa of having murdered the boy in the hope of enjoying the throne together with a secret lover. The King summons Elsa to answer the charge and decrees trial by ordeal of battle. Commanded to name her champion, she tells of a knight seen in a dream: upon him alone will she rely. Not until the second call of the Herald has gone out and Elsa has fallen to her knees in prayer does the champion appear. He is a knight in shining white armor who comes in a boat drawn by a swan. He accepts the gage of battle, after asking Elsa whether or not she wants him to be her husband if victorious in the combat, and exacting a promise never to ask of him whence he came or what his name or race. He overcomes Telramund, but gives him his life; the King, however, banishes the false accuser and sets the stranger over the people of Brabant with the title of Protector. Telramund is overwhelmed by his misfortunes, but Ortrud urges him to make another trial to regain what he has lost. The knight, she says, had won by witchcraft, and if but the smallest joint of his body could be taken from him, he would be impotent. Together they instil disquiet and suspicion into the mind of Elsa as she is about to enter the minster to be married. After the wedding guests have departed, her newly found happiness is disturbed by doubt, and a painful curiosity manifests itself in her speech. Lohengrin admonishes, reproves, and warns in words of tenderest love. He had given up greater glories than his new life had to offer out of love for her. A horrible fear seizes her: he who had so mysteriously come would as mysteriously depart. Cost what it may, she must know who he is. She asks the question, but before he can reply Telramund rushes into the room with drawn weapon. Elsa has but time to hand Lohengrin his sword, with which he stretches the would-be assassin dead on the chamber floor. Then he commands that the body be carried before the King, whither he also directs her maids to escort his wife. There is another conclave of King and nobles. Lohengrin asks if he had acted within his right in slaying Telramund, and his deed is approved by all. Then he gives public answer to Elsa's question:
